I was listening to HANE from Umineko when I got to that last page, and, honestly, it fit the scene with Rentarō perfectly, somehow. Rentarō probably couldn't solve Umineko, though. Probably.
I like how Nozawa-senpai drew the monk always smiling and happy but the dialogue is him screaming like a drill sergeant.
Mei and Iku were not a combo I saw coming but this chapter was great.
